Pharyngeal swab sampling method based on visual analysis

Abstract

The invention discloses a throat swab sampling method based on visual analysis, and the method comprises the following steps: 1, clamping a throat swab through a multi-degree-of-freedom mechanical arm, and stretching the throat swab into the oral cavity of a patient; 2, scanning the oral environment of the patient based on a visual acquisition module, obtaining oral point cloud data, and constructing an oral three-dimensional scene; 3, performing visual analysis on the oral cavity three-dimensional scene to obtain space coordinates of small tongues, teeth and palate organs in the oral cavity; and 4, determining a sampling path of the real-time throat swab according to the space coordinates of the small tongue, the teeth and the palate organ, and controlling the multi-degree-of-freedom mechanical arm to perform sampling operation based on the real-time sampling path. The preset sampling path can be corrected in real time, so that real-time sampling can be performed according to the oral cavity characteristics of the person to be sampled, and the sampling precision is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of throat swab sampling, in particular to a throat swab sampling method based on visual analysis. Background technique [0002] Pharyngeal swab collection is an essential link in the treatment of new coronary pneumonia. Pharyngeal swab collection and bacterial culture can isolate pathogenic bacteria, which is the most important sampling method for the diagnosis of new coronavirus infection. At present, throat swabs are obtained by manual sampling. During the collection process, medical staff must have close contact with patients. Patients coughing and breathing hard will produce a large number of droplets or aerosols, which has a high risk of cross-infection. [0003] However, the sampling steps of the existing sampling device have the following problems: 1. The sampling trajectory is not adapted to the characteristics of the oral cavity of the person, so that the sampling trajectory of everyone is the same;...

Problems solved by technology

At present, throat swabs are obtained by manual sampling. During the collection process, medical staff must have close contact with patients. Patients coughing and breathing hard will produce a large number of droplets or aerosols, which has a high risk of cross-infection

[0003] However, the sampling steps of the existing sampling device have the following problems: 1. The sampling trajectory is not adapted to the characteristics of the oral cavity of the person, so that the sampling trajectory of everyone is the same; 2. The sampling intensity cannot be adjusted in real time, making it easy to cause The subject is unwell
